These two fertilizations were not sufficient to guarantee the maintenance of available phosphorus levels in the years after the application of the program. In the Southern temperate part of Chile, andisols are the dominant soil type. The quantities of lime provided initially must be reconsidered and, most of all, it yy necessary to repeat the liming every years in order to have more lasting enncalado on the pH and, consequently on the exchangeable Al content.
P-Olsen measured in different localities of the precordillera and the cordillera, Araucania Region south of Chile. The program focuses on improving the availability of phosphorus through phosphate supplements and liming, in order to decrease acidity and the content of free aluminium in the soil. Andisols, phosphorus, aluminium toxicity, soil acidity.
Instituto de Investigaciones Agropecuarias, Santiago, Chile, pp. Application of the program had different effects on the pH of the soil in the different locations studied Table 3. At Lonquimay P-Olsen was initially increased, showing a positive short-term effect of the program, but gradually decreased after the first year, until it returned to the initial level.
However, these have been seldom applied in the area object of this study, and therefore they will not be discussed in this paper.
Acidez de los suelos y efectos del encalado
Spanish words that begin with e. Our method was based on the comparison of native pastures with farmers’ grasslands after they have received, 1 to 4 years before our survey, the program actions. Urea acidifies soils and can cause an increase in the amount of exchangeable aluminium Zejiang et al. A sample of 2. Influence of agricultural pratices on the stability of organic-Al complexes in alu-andic andosol: Examples of use in the Spanish literature, quotes and news about encalado.
Cultivation practices in the five localities studied. We also share information about the use of the site with our social media, advertising and analytics partners. Chemical properties of volcanic soils affected by seven-years rotations. The phosphorus was determined by colorimetry with the blue of molybdene method, using ascorbic acid as a reducing agent.
The program also includes other actions such as the creation of terrasses to prevent erosion, the set up of cover-crops.
Conocidos estos datos pueden adoptarse las siguientes directrices: For the analysis of exchangeable aluminium, 5 g of dry soil were added to a solution of ammonium acetate 1M, and shaken for 30 minutes, before acidex. In those locations, phosphorus uptake by grasses was hampered by the presence of free aluminium.

Soil Science Society of America Journal 76 2 Synonyms and antonyms of encalado in the Spanish dictionary of synonyms. The findings are not similar to those of Verde et al. Site description and experimental settings. This program has been operational for more than a decade.
Temperate pasture legues in Australia – their history, current use and future prospects. Spanish words that begin with acidezz.
This whole strategy is essential to keep a sufficient proportion of legume species in the pastures. Phosphoric fertilizers affect directly phosphorus availability Helyar, Alex values were not significantly different between the first and the encalao year, but exhibiting a slight decrease during the period at Cunco.

Each value in tables 3 – 5 is the average of 4 to 8 measured values. The chemical behavior of aluminium, hydrogen and manganese in acid soils, in: Such strategy should be based on a balance of P that takes into account the increase of output due to the increase of the pasture productivity.
We analysed the soil in those fields, for two consecutive years, characterized by very different weather conditions: De la Fuente, J.
Advances in Agronomy 66, This explanation is more likely than the fixation by the soil, as the content of extractable aluminium is less than mg kg In a similar way to liming, the phosphoric fertilization must be part of a global strategy for impro ving P availability.
